Since July 1, 2017, electronic invoicing has been mandatory for all Business-to-Government (B2G) transactions in Lithuania. Initially facilitated through the eSąskaita platform, this system was replaced by the General Information System for Account Administration (SABIS) in September 2024. The transition aimed to modernize the invoicing process, enhance efficiency, and align with European Union standards, particularly Directive 2014/55/EU on electronic invoicing in public procurement.
The SABIS platform supports the Peppol BIS Billing 3.0 and Peppol BIS Billing CII Invoice formats, ensuring compliance with EU e-invoicing standards. Invoices can be submitted via the SABIS web portal, direct API integration, or through the Peppol network, which facilitates cross-border electronic invoicing. As a certified Peppol Access Point, B2Brouter enables seamless integration with SABIS, allowing businesses to transmit invoices efficiently and securely.
This forthcoming mandate underscores the importance for companies operating in Lithuania to familiarize themselves with the current e-invoicing infrastructure and prepare for broader compliance requirements.
